The Axis series is a performance vest that features ease of entry due to a shorter zipper and open neck profile. Mobility and simple fit is standard on these vests thanks to enlarged arm holes. A segmented horizontal hinge line in the buoyancy foam on the chest allows the vest to bend forward easily. The Ergolite foam is the lightest weight foam available and has compression and elasticity that gives a custom feel without retaining water.Coast Guard Type: USCG Type lllFlotation Material: PVC foam
